Abstract

Embodiments of the present disclosure includes systems and methods for diagnosing and correcting deficiencies in operation of integrated circuits. A set of operational data of an integrated circuit is received by a network via a communication interface. A deficiency in operation of the integrated circuit is diagnosed based on the set of operational data. A correction is generated for improving operation of the integrated circuit based on the deficiency diagnosed. The correction is transmitted over the network via the communication interface to the integrated circuit.
